Prevalence and relevance of impaired left ventricular function in chronic moderate regurgitation of native aortic valves

Background: Reduced ejection fraction (EF) in chronic moderate aortic regurgitation (AR) could be either due to a late remodelling response after longstanding moderate AR, or could represent a specific phenotype of cardiomyopathy (CMP) with concomitant AR. The aim of this study was to analyse progression of left ventricular (LV) impairment in moderate AR.Methods: All patients in our echocardiography database between 2005 and 2016 were screened...
